2005 Hyundai Tucson P1491 Code: Meaning and Diagnosis - Running Fine but Code Detected

Model: 2005 Hyundai Tucson Fault Code: P1491 Posted: 2010-08-28 13:14

I recently received a P1491 diagnostic code from my 2005 Hyundai Tucson, but the definition is showing as 'definition not found' when I attempt to read it. The vehicle appears to be running normally with no noticeable performance issues. Can anyone clarify what the P1491 code means in this context? Is it related to the oxygen sensor or exhaust system? Any insights into potential causes or solutions would be greatly appreciated.
